✦ Synopsis

Alkyl thiyl radicals produced by the homolytic decomposition of thionitrites are detected by ESR spin trapping using 5,5-dimethyl-1-A-pyrroline-N-oxide (DMPO). Alkyl thionitrites (RSNO; thionitrous acid esters) have been prepared by nitrosation of thiols with alkyl nitrites (11, N204 (2), and other agents. Most thionitrites are both thermally (3)

Shortly after their formation, transient free radicals trapped in micelles exhibit electron spin resonance (ESR) spectra with "antiphase" lineshapes, i.e. lines with their low-field halves in emission and high-field halves in absorption. It is demonstrated that this hitherto unexplained effect is co
